Product details
Overview
DS1010-400 from Dallas Semiconductor is a 10-tap all-silicon delay line with nominal total delay of 400 ns, ±5% or ±2 ns tolerance, TTL/CMOS-compatible input/output, and 5 V supply. It delivers precise leading and trailing edge delays across ten equally spaced taps (40 ns/tap), and drives up to 10 × 74LS loads per tap. Used in digital timing alignment, clock skew correction, and pulse shaping circuits.
For engineers reviewing the DS1010-400 datasheet, DS1010-400 pinout, DS1010-400 application, or DS1010-400 equivalent, key selection factors include tap-to-tap uniformity, edge accuracy specification, 14-pin DIP vs. 16-pin SOIC package options, temperature-dependent delay shift (±2 ns or ±3% for ≥100 ns variants), and load-driving capability per output.
Technical Context
The DS1010-400 implements a monolithic CMOS delay chain architecture with fixed, equally spaced taps-no programmability or external control. All ten outputs reproduce the input logic state with deterministic propagation delay, maintaining identical tPLH and tPHL characteristics within ±2 ns or ±5% tolerance.
Delay stability is achieved via matched transistor sizing and layout symmetry; temperature-induced drift follows unidirectional variation (e.g., if TAP 1 slows, all taps slow proportionally). Input pulse width must exceed 40% of TAP 10's tPLH (≥160 ns) to maintain specified accuracy.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Total Delay | 400 ns nominal at TAP 10; defines maximum fixed latency for signal alignment tasks |
| Delay/Tap | 40 ns; enables fine-grained timing resolution for multi-stage synchronization | Delay Tolerance | ±5% or ±2 ns (whichever greater); sets worst-case timing margin for setup/hold validation |
| Supply Voltage | 4.75 V to 5.25 V; compatible with standard 5 V TTL/CMOS logic rails |
| Output Drive | 12 mA sink / –1 mA source; supports direct interface to 10 × 74LS loads without buffering |
| Operating Temp | 0°C to +70°C; industrial-grade range suitable for non-automotive embedded systems |
| Input Capacitance | 5–10 pF; low loading minimizes signal integrity impact on driving gate |
Pinout & Package
DS1010-400 is available in two packages: 14-pin DIP (300-mil) and 16-pin SOIC (300-mil). Pin assignments differ between packages; the DIP version uses pins 1–14, while the SOIC version adds two NC pins (15, 16) and reorders some taps. Both are auto-insertable and vapor-phase solderable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Signal Input | Accepts TTL/CMOS-compatible logic pulses; 5–10 pF input capacitance limits high-frequency ringing |
| TAP 1–TAP 10 | Delayed Output | Fixed-delay outputs (40 ns increments); each drives ≤10 × 74LS loads; no internal termination |
| VCC | Power Supply | +5 V supply rail; requires local 0.1 µF bypass capacitor near pin for stable delay performance |
| GND | Ground Reference | Common return path for all I/O and supply; critical for minimizing ground bounce-induced jitter |
| NC | No Connection | Unbonded pins (DIP: pins 3, 4, 8, 11; SOIC: pins 2, 15, 16); must remain floating or grounded per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon construction | Eliminates hybrid ceramic delay line cost and reliability risks; enables automated PCB assembly |
| Equal tap spacing (40 ns) | Enables predictable phase-shifted sampling or staggered enable sequencing without recalibration |
| Leading/trailing edge accuracy | Ensures symmetrical delay for both rising and falling edges-critical for PWM and clock distribution |
| ±5% or ±2 ns delay tolerance | Provides known worst-case timing budget for synchronous logic design and skew analysis |
| Low-power CMOS operation | Typical ICC = 40–150 mA; reduces thermal load in dense timing-critical layouts |

IC Role / Device Role / Timing Role: Inserted in the clock or data path to realign skewed signals before latch decision point. Use Value: Restores timing margin lost due to unequal PCB trace lengths without requiring layout revision. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-tap delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MC100EP195FA | 10-tap ECL delay line; 3.3 V supply; ±0.35 ns typical jitter; higher speed but incompatible voltage domain | Used in RF and high-speed serial links where sub-ns precision outweighs power and compatibility constraints | Select when interfacing with ECL/PECL logic and requiring <1 ns edge jitter; not drop-in for 5 V TTL systems |
| Analog Devices AD9501 | Programmable 8-tap delay IC; 3.3 V; SPI-configurable; ±50 ps resolution; includes internal PLL | Suitable for adaptive delay calibration, not fixed-latency alignment | Choose when dynamic delay adjustment or integration with clock synthesis is required; DS1010-400 offers lower cost and zero configuration overhead |
Compared with MC100EP195FA and AD9501, the DS1010-400 delivers deterministic 400 ns latency with zero configuration, 5 V compatibility, and proven stability across industrial temperature range-making it optimal for cost-sensitive, fixed-delay embedded timing where programmability or ultra-low jitter are unnecessary.

FAQ
What is the exact total delay specification for DS1010-400?
The DS1010-400 provides a nominal total delay of 400 ns at TAP 10, with a tolerance of ±5% or ±2 ns (whichever is greater) under standard conditions (VCC = 5.0 V ± 5%, TA = 25°C). This delay applies to both rising (tPLH) and falling (tPHL) edges, and remains stable across the full operating temperature range (0°C to +70°C).
Does DS1010-400 support both 14-pin DIP and 16-pin SOIC packages?
Yes, DS1010-400 is offered in both 14-pin DIP (300-mil) and 16-pin SOIC (300-mil) packages. The DIP version uses pins 1–14 with specific tap ordering, while the SOIC version adds two NC pins (15 and 16) and rearranges several tap positions. Pin compatibility is not maintained between packages-PCB layout must match the selected variant.
How many logic loads can each tap of DS1010-400 drive?
Each tap of DS1010-400 is rated to drive up to 10 × 74LS-type loads, corresponding to a low-level output current (IOL) of 12 mA and high-level output current (IOH) of –1 mA. This drive strength ensures reliable fanout without external buffers in standard TTL/CMOS systems operating at 5 V.
Is DS1010-400 compatible with 3.3 V logic systems?
No, DS1010-400 is specified only for 5 V operation (VCC = 4.75 V to 5.25 V) and features TTL/CMOS-compatible input thresholds (VIH ≥ 2.2 V, VIL ≤ 0.8 V). It is not designed for direct interface with 3.3 V logic families; level-shifting circuitry is required for interoperability with 3.3 V systems.
What is the maximum recommended input pulse width for DS1010-400?
The DS1010-400 requires an input pulse width (tWI) of at least 40% of TAP 10's tPLH delay-i.e., ≥160 ns-to maintain specified timing accuracy. Shorter pulses may cause degraded delay precision due to internal node settling effects, especially at temperature extremes or supply variations.
